Abstract
The invention discloses a foundation reinforcement structure of a construction refuse dump on soft soil, aiming at providing a foundation reinforcement structure, which has the characteristics of simple structure, easiness for construction and good durability and is beneficial to effective decrease of construction cost. The foundation reinforcement structure comprises a lower hard-soil-coating layer (10), a soft soil layer (11), a construction refuse layer (12) and an upper filling layer (40) from the bottom up, wherein reinforcement piles (20) penetrating through the construction refuse layer (12) and the soft soil layer (11) longitudinally and transversely are arranged below the upper filling layer (40), and the reinforcement piles (20) are formed by compounding concrete mix piles (21) penetrating through the soft soil layer (11) and pile hammer expanding piles (22) penetrating through the construction refuse layer (12).
Description
Technical field
The present invention relates to the ground stabilization structure, particularly a kind of building waste field and quarrel are the ground stabilization structure of weak soil after the match.
Background technology
Along with accelerating development of urbanization construction, a large amount of building wastes has appearred, and there is a large amount of building wastes to abandon on soft foundation, particularly this situation in coastal cities is more general.Because the continuous expansion of city size, it is more and more on soft foundation building waste field, to build engineering, and in view of building waste and weak soil particularity separately, the single reinforcing engineering measure is difficult to engineering demands or construction investment is huge.Therefore, a kind of can being convenient to of active demand constructed in weak soil layer and building waste, can satisfy the simple ground stabilization new construction of requirement of engineering and construction technology again, and meet environmental protection requirement.
Summary of the invention
Technical problem to be solved by this invention provides on a kind of weak soil building waste field ground ruggedized construction structure, have simple in structure, construction easily, the characteristics of good endurance, reduced investment.
The technical solution adopted for the present invention to solve the technical problems is following:
Building waste field ground is reinforced structure on the weak soil of the present invention; Its ground comprises that following hardpan, weak soil layer, building waste layer and the top covered from bottom to top fills layer; It is characterized in that: the reinforcing stake that fill below the layer vertically on said top, horizontally set passes building waste layer and weak soil layer, said reinforcing stake are developed by concrete mix stake of passing the weak soil layer and the post hammer that passes the building waste layer and compound are constituted.
Said top is filled between layer and the building waste layer and is equipped with reinforced rubble bed course (30).
The invention has the beneficial effects as follows that simple in structure, construct easy, good endurance can effectively be reducingd the construction costs, and compliance with environmental protection requirements, thereby have broad prospect for its application.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the schematic cross-sectional view that building waste field ground is reinforced structure on the weak soil of the present invention;
Fig. 2 is the local enlarged diagram of A among Fig. 1.
Position shown in the figure, member and pairing mark: cover down hardpan 10, weak soil layer 11, building waste layer 12, reinforce stake 20, stake 22 is developed in concrete mix stake 21, post hammer, layer 40 is filled on reinforced rubble bed course 30, first floor macadam 31, first geogrids layer 32, second macadam 33, second geogrids layer 34, the 3rd macadam 35, top.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
With reference to Fig. 1, building waste field ground is reinforced structure on the weak soil of the present invention, and its ground comprises that following hardpan 10, weak soil layer 11, building waste layer 12 and the top covered from bottom to top fills layer 40.Said top fill layer 40 below vertically, the horizontally set reinforcing stake 20 of passing building waste layer 12 and weak soil layer 11, saidly reinforce stake 20 and develop 22 by concrete mix stake of passing weak soil layer 11 21 and the post hammer that passes building waste layer 12 and compoundly constitute.
Concrete mix is adopted in said concrete mix stake 21, and according to weak soil layer pile-forming effect decision concrete grade, concrete grade is not less than C15, requires the concrete mix pile-forming effect to be not less than the granular pile effect.Said post hammer develops stake 22 and places in the concrete mix stake 21, treat concrete mix stake 21 initial sets after construction post hammer develop stake, the 2m stake long column hammer that joins with concrete mix stake 21 develops energy should suitably be reduced.
With reference to Fig. 1, said top is filled between layer 40 and the building waste layer 12 and is equipped with reinforced rubble bed course 30.With reference to Fig. 2, said reinforced rubble bed course (30) can be made up of the first floor macadam of from bottom to top laying successively 31, first geogrids layer 32, second macadam 33, second geogrids layer 34 and the 3rd macadam 35.Said first geogrids layer 32 and second geogrids layer 34 adopt the low two-way GSZ of strain high strength, and its ultimate tensile strength is not less than 80kN/m, and the nominal strength elongation per unit length is not more than 10%, mesh size 80～150mm.
The present invention makes full use of the pile of concrete mix in weak soil, forms concrete mix stake 21 and overcomes bulk solid stake pile difficulty in the weak soil, forms the displacement stake.Adopt the post hammer to develop stake 22 on the top of concrete mix stake 21 and reinforce building waste layers 12, give full play to the compacted effect that the post hammer develops 22 pairs of waste layer of stake and develop 22 an own carrying effect with the post hammer.30 of reinforced rubble bed courses improve bearing capacity of foundation soil and basic evenly distributedly bearing capacity.Compare with existing single reinforcing engineering measure, simple in structure, the characteristics easy, good endurance of constructing that the present invention has, and can reducing the construction costs effectively, and compliance with environmental protection requirements, thereby have broad prospect for its application.
Building waste field ground is reinforced some principles of structure on the above weak soil of the present invention that just explains through diagrams; Be not be to the present invention be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
